Modeling flow of porous medium with coulomb friction on walls of ducts

Abstract eng:
The paper deals with development of a computational model describing oil expression from oil-containing seeds. The principles of compression in the rotating screw pressing machine are based on interplay between the screw rotor geometry, the related kinematics and the friction forces acting on the surfaces of the rotor and stator of the machine. We consider a poroelastic biphasic material of the Biot type. The deformation is described using a combination of the spatial and material formulations. Within one time increment step, the physical fields involved in the problem are analyzed using the Lagrangian configuration
